In any industry, safety is always a top priority. This is especially true in the oil and gas industry, where a small mistake can have catastrophic consequences. That is why it’s so crucial to have a regular inspection regime in place for all critical components of your operation. One of the most critical inspections you may perform is an API 653 inspection.
API 653 is the industry-standard practice for inspecting Aboveground Storage Tanks (ASTs). These tanks are generally used to store a variety of liquids, including petroleum products, chemicals, and water.
An API 653 inspection is a thorough examination of the tank and its components so that any potential problems may be identified and rectified before they cause an accident.
In this article, we’ll take a look at the four most critical components of an API 653 inspection that any business operating ASTs should be aware of. So, without further ado, let’s begin!

1. The Tank Shell
The first and most important component of an API 653 inspection is the tank shell. The shell is the part of the tank that holds the liquids, so it’s crucial that it is in good condition and free from any defects.
The inspector will check the shell for any signs of corrosion, cracking, or other damage. They will also check the tank’s supporting structure to make sure that it is strong enough to support the weight of the liquids in the tank.
2. The Tank Bottom
The second critical component of an API 653 inspection is the tank bottom. The bottom of the tank is where any sediment or sludge will settle, so it’s important that it is inspected regularly.
The inspector will check the bottom of the tank for any signs of corrosion or cracking. They will also check the tank’s drains and other openings to make sure that they are clear and not obstructed. If the bottom of the tank is not in good condition, it could cause the tank to leak or even collapse.
3. The Tank Roof
The third critical component of an API 653 inspection is the tank roof. The roof of the tank is what protects the liquids inside from exposure to the elements. It is also the part of the tank that is most susceptible to damage from wind, rain, and snow. Thus, it’s important that the roof is inspected regularly.
In order to check the condition of the roof, the inspector will climb up onto the tank and visually inspect it for any signs of damage. They will also check the seals around the roof to make sure that they are intact and not leaking.
4. The Tank Appurtenances
The fourth and final critical component of an API 653 inspection is the tank’s appurtenances. Appurtenances are the components of the tank that are not permanently attached, such as the floating roof, ladders, and handrails.
It is important to inspect the condition of these components regularly, as they are susceptible to damage from the elements. The inspector will check for any signs of corrosion or damage and make sure that all the bolts and fasteners are tight.
Make Sure Your API 653 Inspection is Thorough and Accurate
API 653 inspections are an important part of any tank storage operation, and by understanding the four critical components of an inspection, you can be sure that your tanks are safe and in compliance with all regulations.
Just remember, an API 653 inspection is only as good as the inspector performing it. So, be sure to hire a qualified and experienced inspector to carry out your next API 653 inspection!
